A Quick Guide to Using WiFi and Mobile Networks on the London Underground

Riding the London Underground is an adventure in itself whether you’re darting between meetings, exploring the city’s hidden gems, or simply commuting home. But in a world where staying online is essential, losing signal underground can be a real hassle. The good news? With expanding WiFi and mobile coverage, you can now stay connected below the city streets. If you’re a Lyca Mobile user or considering options like Pay As You Go SIMs, this quick guide is for you! 

Where Can You Access WiFi on the London Underground? 

WiFi is available at all London Underground stations, most London Overground stations, and all Elizabeth line stations under central London. However, WiFi is only available on station platforms, ticket halls, and walkways—not in the tunnels or between stations. When your train is moving, you’ll lose the WiFi connection, but your device will automatically reconnect when you arrive at the next WiFi-enabled station. 

How to Connect to London Underground WiFi 

Connecting to WiFi on the Tube is straightforward: 

  • Enable WiFi on your device before entering the station.
  • Search for available networks in your WiFi settings. Look for networks named after major UK providers, such as:
  • EE WiFi-Auto
  • Wifi Extra (O2)
  • Three_WIFI
  • VodafoneWiFi
  • The Cloud (on London Overground)
  • Select the network and follow any on-screen prompts. Some networks may require you to accept terms and conditions or sign up the first time you connect.
  • Automatic reconnection: Once set up, your device should auto-connect to the WiFi network whenever you’re in range at a participating station. 

Tip: If you’re connecting during peak hours, it may take a few extra seconds for your device to join the network due to high demand. 

Mobile Network Coverage Underground 

4G and 5G mobile coverage is being rolled out across the Underground, including stations, platforms, and even tunnels on several lines. This means that in many areas, you can now use your mobile data, make calls, and send texts without interruption just as you would above ground. 

Where is Mobile Coverage Available? 

Line Coverage Areas 
Central Shepherd’s Bush to Bank (stations & tunnels) 
Jubilee Westminster to Canning Town (stations & tunnels) 
Piccadilly Hyde Park Corner to King’s Cross & St Pancras International (stations & tunnels) 
Victoria Green Park to King’s Cross & St Pancras International (tunnels) 
Northern Highgate/Hampstead to Embankment (Charing Cross branch); Kennington to Clapham South (southern section) 
Elizabeth Line All stations and tunnels 
Bakerloo Embankment, Charing Cross, and Piccadilly line platforms, and tunnel sections between Oxford Circus and Embankment 

If your station or line doesn’t yet have mobile coverage, you can still rely on WiFi at stations. 

Lyca Mobile: Stay Connected Underground 

As a Lyca Mobile customer, you have several options to stay connected: 

  • Pay As You Go SIM only deals: Top up and use data as needed ideal for occasional Tube travellers or visitors.
  • Pay monthly SIM only deals: For regular commuters, these plans offer generous data allowances and seamless connectivity.
  • eSIM: Instantly activate your Lyca Mobile plan without a physical SIM card perfect for newer smartphones and international visitors. 

 

If you need to use your phone for data while in tunnels, ensure your device is 4G/5G compatible and your Lyca Mobile plan includes data roaming if you’re visiting from abroad. Lyca Mobile offers affordable EU roaming and data roaming options, so you can avoid bill shocks and stay online wherever your journey takes you. 

For even more value, check out pay monthly SIM only rates for flexible, budget-friendly options. 

Tips for a Seamless Underground Connection 

  • Enable WiFi and mobile data before entering the station.
  • Download necessary apps or files before your journey, as connectivity in tunnels is still limited in some areas.
  • Use eSIM for instant activation if you’re arriving in London and want to avoid the hassle of finding a physical SIM card.
  • Check your data allowance or top up your Pay As You Go SIM only before travelling.
  • Contact Lyca Mobile customer service if you experience issues connecting to WiFi or mobile networks on the Underground.
